LIFE 102 Lecture Notes - Metabolic Pathway, Emergence, Chemical Energy
Document Summary
A reasonable daily diet for an adult is 2000 food calories. 1 calorie raises temperature of 1 gm of water by 1 degree c. Concept 8. 1: an organism"s metabolism transforms matter and energy, subject to the laws of thermodynamics. Metabolism is the totality of an organism"s chemical reactions. Metabolism is an emergent property of life that arises from interactions between molecules within the cell. Metabolism refers to all the chemical reactions that occur in a living creature. Catabolic pathways release energy by breaking down complex molecules into simpler compounds. Cellular respiration, the breakdown of glucose in the presence of oxygen, is an example of a pathway of catabolism. Anabolic pathways consume energy to build complex molecules from simpler ones. The synthesis of a protein from amino acids is an example of anabolism. Organization of the chemistry of life into metabolic pathways. A metabolic pathway begins with a specific molecule and ends with a product.
